HEAT PUMP SYSTEM IN VEHICLE

摘要

PURPOSE: A heat pump system for vehicles is provided to assist an outdoor heat exchanger in smoothly absorbing heat. CONSTITUTION: A heat pump system for vehicles comprises a compressor, a pair of indoor heat exchangers, and a pair of outdoor heat exchangers. The compressor is connected to two refrigerant loops through a fluid path(F). The pair of outdoor and indoor heat exchangers is placed in the two refrigerant loops. The pair of outdoor and indoor heat exchangers is placed to be overlapped in upper and lower directions of an air flow. The refrigerant loops respectively comprise the indoor and outdoor heat exchangers. The refrigerants discharged from the compressor respectively circulate in the two refrigerant loops, and are sucked into the compressor again.
